My recently purchased 64GB Extreme is not recognised when plugged into my laptop PC's USB 3.0 port.
It works fine when plugged into a USB 2.0 port but that's not what I bought it for.
Very occasionally when plugged into a USB 3.0 port it will show up for a minute or two but then disappears again.
There is no message displayed to say it's not recognised nor is there any indication of any sort in Device Manager. It just isn't there.
Is there any way to resolve this problem?
I am using Windows 7 64-bit.

I've already done that. Didn't make the slightest bit of difference.
When I plug my USB 3.0 external hard drive into the USB 3.0 port the SanDisk Extreme was in it works perfectly. Take it out and put the SanDisk back in .... nothing.
Clearly the problem is with the SanDisk Extreme and it's USB 3.0 compatability. (As I mentioned above, when it is plugged into a USB 2.0 port it works just fine).

Saw this thread from January. My extreme 32GB was working fine yesterday. This morning it's not recognized as a USB 3.0 device on 3 different (nearly identical) PC's. Nothing has changed so I'm mystified. Works fine as a USB 2.0 drive.
The original poster never updated this thread, so I don't know how -- or if -- he solved his problem.

Therefore think this is probably a design fault with the connector, although it does seem that once it's recognised, it can be pushed in properly again.

I can think of other possible causes:
cigarette smoke on the USB port
oxidation of the USB port
loose wire on the USB port.
I have at least one USB port in the back of my desktop machine that I periodically have to touch with emory paper to get it to work normally again.

Thanks for that tip. That did the trick for me. I remove it completely then push it in very slowly, when I see the light light up, I hear the windows tone, then my sandisk is recognized. Then I can push it in all the way and it will work until I unplug it. Definitely sounds like a design issue or hardware flaw on my usb drive

Same issue here. 32GB SanDISK Ultra. Not recognized in laptop nor PC. It used to work for a while.
